MySQL fails to run on Github Actions using Kind #1179

tamalsaha · 2019-12-18T07:13:23Z

What happened:
We are trying to run an official MySQL pod inside a Kind cluster on GitHub actions. Here is our demo repo: https://github.com/tamalsaha/mysql-kind-demo

The problem is mysql pod fails to run with the error message:

+ mysqld --verbose --help
mysqld: Can't read dir of '/etc/mysql/conf.d/' (OS errno 13 - Permission denied)
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!

You can see the full log here: https://github.com/tamalsaha/mysql-kind-demo/commit/dfef4e188accdb6334b75f4658bd0fc1dd35c732/checks?check_suite_id=364071606

The puzzling this is that if I just run docker run mysql:8.0.14 mysqld --verbose --help it works! You can see full log here:
https://github.com/tamalsaha/mysql-kind-demo/commit/d452e672fa2219fb5ea5174bd99108d6d0b2728a/checks?check_suite_id=364034120

When I try these on my Ubuntu 18.04 Desktop (using pod in a Kind cluster and Direct Docker), both modes work.

You can see the diff between pod log from my Desktop (left) and Github action (right). They mostly look identical: https://www.diffchecker.com/D64wMscf

Can you help my understand why mysqld --verbose --help fails when run as a pod inside a Kind v1.16.3 cluster on GitHub actions?

What you expected to happen:

How to reproduce it (as minimally and precisely as possible):

Here is our demo repo: https://github.com/tamalsaha/mysql-kind-demo

If you want to run locally, try this:

kind create cluster
kubectl apply -f https://github.com/tamalsaha/mysql-kind-demo/raw/master/hack/kubernetes/mysql.yaml

Anything else we need to know?:

One hack we found is that if we mount an emptyDir to /etc/mysql/conf.d folder, mysqld --verbose --help command starts working.

When I try these on my Ubuntu 18.04 (using pod in a Kind cluster and Direct Docker), both modes work.

indeed, this smells to some filesystem permissions ... 🤔 I wonder if there are some restrictions on the docker folders https://help.github.com/en/actions/automating-your-workflow-with-github-actions/virtual-environments-for-github-hosted-runners

aojea · 2019-12-18T09:03:05Z

@tamalsaha seems you are using https://github.com/engineerd/setup-kind
Can you open an issue there and reference this one?
maybe the author of that project is more familiar with Github Actions and can shed some light on this issue

BenTheElder · 2019-12-18T10:46:19Z

Without looking too closely yet this sounds like a PV using fsGroup, that won't work out of the box until the next kind release. If you use kind from HEAD it should work.

BenTheElder · 2019-12-18T10:49:15Z

https://github.com/tamalsaha/mysql-kind-demo/blob/master/.github/workflows/ci.yml even has the logic to setup the rancher driver, just commented out ...?

tamalsaha · 2019-12-18T10:49:53Z

I am going to try kind from HEAD and report back. But /etc/mysql/conf.d folder is not mounted to any disk. This is just Docker overlay fs.

For this test, we don't need the rancher driver.

tamalsaha · 2019-12-18T11:42:42Z

I have tried Kind from HEAD and I am still getting the same error.

https://github.com/tamalsaha/mysql-kind-demo/blob/master/.github/workflows/kind-master.yml

https://github.com/tamalsaha/mysql-kind-demo/commit/1bfb9bf8ad3260a1314d391c6a352f4eb07c33ba/checks?check_suite_id=364450794

tamalsaha · 2019-12-18T21:36:43Z

There is something particularly weird about the virtual environment provided by GitHub actions. I created a similar machine DigitalOcean with uname -a

root@kind-mysql-1904:~# uname -a
Linux kind-mysql-1904 5.0.0-31-generic #33-Ubuntu SMP Mon Sep 30 18:51:59 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Then creates a kind cluster and everything worked.

I also added strace to the mysql image and you can see the error:

I am going to try kind from HEAD and report back. But /etc/mysql/conf.d folder is not mounted to any disk. This is just Docker overlay fs.

ah, this is a directory in the mysql image? not a hostPath or a volume? I saw a PVC in your manifests when I took a quick look last night and guessed wrongly :-)

tamalsaha · 2019-12-18T21:42:25Z

ah, this is a directory in the mysql image?

Yes. https://github.com/docker-library/mysql/blob/75f81c8e20e5085422155c48a50d99321212bf6f/8.0/Dockerfile#L69

BenTheElder · 2019-12-18T21:44:38Z

docker-library/mysql#484 🤔

BenTheElder · 2019-12-18T21:48:02Z

seeing a few comments around that suggest a relation to apparmor

tamalsaha · 2019-12-18T21:50:08Z

Do you think https://unix.stackexchange.com/questions/229782/overlayfs-doesnt-work-with-unprivileged-user-namespace might be somehow related?

The thing is I can ls -l /etc/mysql/conf.d, I can touch a new file from that directory inside the pod. Why does mysqld fails?

BenTheElder · 2019-12-18T21:52:10Z

Do you think https://unix.stackexchange.com/questions/229782/overlayfs-doesnt-work-with-unprivileged-user-namespace might be somehow related?

possibly. I don't know how github actions setup docker in this environment or what security mechanisms / filesystems they have enabled...

tamalsaha · 2019-12-18T21:53:08Z

GitHub uses packer to build their VM. https://github.com/actions/virtual-environments

BenTheElder · 2019-12-18T21:59:02Z

can you test #1183 ?
not sure the best way to get it into your github actions (could clone it, check out the ref, make install?)

tamalsaha · 2019-12-18T22:00:07Z

Checking from your fork.

tamalsaha · 2019-12-18T22:14:16Z

I used your fork tamalsaha/mysql-kind-demo@913a250

But I'm still getting the same error:

https://github.com/tamalsaha/mysql-kind-demo/commit/badf26c75ba55d007e96ee0807af1c8d4b42f1f2/checks?check_suite_id=365558618

BenTheElder · 2019-12-19T20:04:55Z

:/

Can you obtain some more details about the github actions environment?

what docker version / how was it installed (snap? etc.?)
how is docker configured? anything interesting like user namespace remapping?
what filesystem is in use and what storage driver?
what permissions does the docker data root have?
what security mechanisms are in use? apparmor? seccomp?

Also, I don't know where to check for:

how is docker configured? anything interesting like user namespace remapping?
what permissions does the docker data root have?

tamalsaha · 2019-12-20T00:57:08Z

@BenTheElder , I think this answer probably gives the clue docker-library/mysql#617 (comment)

I am still trying to understand it.

BenTheElder · 2019-12-20T02:32:23Z

how is docker configured? anything interesting like user namespace remapping?

the daemon config.json. most of this is surfaced in docker info

what permissions does the docker data root have?

this bit from docker info:
Docker Root Dir: /var/lib/docker

that's where docker stores runtime data (containers, images, volumes... )

we can check the permissions on that for sanity

BenTheElder · 2019-12-20T02:40:44Z

@BenTheElder , I think this answer probably gives the clue docker-library/mysql#617 (comment)

ah that makes sense!

BenTheElder · 2019-12-20T02:49:27Z

this explanation is good -- moby/moby#7512 (comment)

an option is to disable apparmor on the host for mysql

kind needs docs for this under known-issues

I'm not sure that we can do much more. kind would of course not run priv containers if we didn't need to, similarly we need to support priv containers inside the kind nodes because kubernetes system components run this way (eg kube-proxy).

containerd / kubelet rootless might be viable in the near future, but it's not quite ready, and i'm not sure if we can ship it right away when it's ready because most of our users's hosts won't be ready kubernetes/enhancements#1371

cgroups v1 -> v2 is going to be "fun" for hacks like KIND 🙃

BenTheElder · 2020-01-02T23:01:15Z

I don't think KIND can do much else here, we should document this in known-issues though.

BenTheElder · 2020-01-07T00:49:37Z

for now documented https://kind.sigs.k8s.io/docs/user/known-issues/#apparmor
